 Re: renaming a directory Peter, This is documented in man mv. A little excerpt: When both source and destination are on the same filesystem, they are the same file (just the name is changed; owner, mode, timestamps remain unchanged). When they are on different filesystems, the source file is copied and then deleted. mv will copy modification time, access time, user and group ID, and mode if possible. When copying user and/or group ID fails, the setuid and setgid bits are cleared in the copy. You could always use touch. mv olddir newdir; touch newdir      |

You aren't changing the contents of the directory, so it's mtime doesn't change. You /are/ changing the metadata about the directory, so it's ctime will change, as will the mtime of the parent directory (the file in which the target directory node is recorded). > If so, is there any way to have it change when it is renamed/moved? Probably. But, you need to alter the contents of the directory in order to alter it's mtime. A rename doesn't alter the contents any. P'haps touch will do.

| Re: renaming a directory Thanks for your reply but I tested with ctime and it also does not change after a directory move/rename: root@marty:/vol3# ls -lhc --full-time drwxr-xr-x 2 root root 48 2006-02-16 15:24:17.000000000 -0500 test/ root@marty:/vol3# mv test test2 root@marty:/vol3# ls -lhc --full-time drwxr-xr-x 2 root root 48 2006-02-16 15:24:17.000000000 -0500 test2/ |

I realized afterword that I was wrong about the ctime. ctime would only change if you changed the directory metadata (extended or truncated the directory, changed it's permission bits, owner, etc.). Since this is a rename, only the parent directory changes, so it's mtime would change. But since a rename doesn't change the target's metadata, the target directory ctime wouldn't change. Sorry for the initial misinformation.
